Dave Brat speaks to supporters after defeating Eric Cantor in Primary

Dave Brat calling this the happiest day of his life, with his "Brat Pack" saying they've done the unthinkable - toppling the second most powerful Republican in congress.

Cantor outspent Brat by millions of dollars, but the overwhelming feeling among supporters is that Cantor became someone too connected with Washington, and not his own backyard.

"The reason we won this campaign is one reason: dollars do not vote, people do," said Dave Brat. "This campaign is about basic American virtues from the beginning. Power belongs to the people and that's what we're going to do. Cheers."

Brat, of course, walked around his victory party very much in a state of shock, saying that he will go to Washington as not a Tea Party Republican, but a classical Republican committed to free market values.

That's only if he beats his Democratic challenger in November, Jack Trammell.
